Application of Airflow Crusher in Solid-State Sodium (Lithium) Battery Production Line

The application of airflow crushers in solid-state sodium (lithium) battery production lines is mainly reflected in the preparation processes of cathode and anode materials, electrolytes, and separators. Specifically, by ultrafine grinding of raw materials, airflow crushers can produce powders with uniform particle size distribution and large specific surface area. These powders exhibit high electrochemical performance, contributing to improved energy density and cycle life of batteries.

Specific Application Scenarios

Preparation of Cathode and Anode Materials: Airflow crushers can grind cathode and anode materials into ultrafine particles with high specific surface area and uniform particle size distribution, which helps enhance the electrochemical performance of batteries.

Electrolyte Preparation: In solid-state batteries, electrolytes are key components. Airflow crushers can perform ultrafine grinding of solid electrolytes, improving their ionic conductivity and processability.

Separator Preparation: Airflow crushers can prepare separator materials with microporous structures. These materials feature uniform pore size and good air permeability, effectively enhancing the charge-discharge performance of batteries.
